Alt del Montnou from Riera de Canalda

The L-401 rises 14.9km through wooded valleys and open mountainside, gaining 1,090m to 1,760m. The average gradient of 7.3% disguises ramps of 16.9% — the kind of gradient that turns plans into prayers. 10 hairpins punctuate the ascent, offering brief respite in the corners before the gradient bites again. The road reaches 1,760m — high enough to feel the altitude on tired legs. Located in Catalonia, Spain.
